This main shaft is operated by a foot lever22 (Figs. '2 and 7).

5 From the'driviug 'shaft23'a frame 43 is moved up'and' down by means of levers and rods 49 combined with which is a spring 49- for the purpose otelantic working (Figs 6 ,smd 7). Thisframe 43' is secured on machine 10 frame 1 and works in a second fixed hoop-like guide or frame 17. This frame 43 carries at its top a'rail 47 placed perpendicular tothe plane of fuel ion, against wluch rail the punching lever 30 provided with a guiding shaft and roller 18 1S pressed by meansof a spring 52, in such a way that onthe frame 43 going downwards the springfil is compressed and the punch 32 moved downwards and caused to produce its effect upon the paper. The

20- sprmg 52 as well as punching lever 30, are

carried by" an arm 33 (Fig. 7) having formed therewith a boss 53 through which the punch 32 moves up and down. This beari'u arm 33 rests at its bottom part on the side 9 (Figs. 4 and 13) guided hetwe entwo rails;

which slide 9, by means of the rod combination 34 and 35-, can, according to requu'el ments, be displaced transversely-to the ion gitudinal direction of the paper band-31 without the starting device of the frame 43.

being thereby interfered with.

ln additionto the ur ose of the roller 18 heriz-iuabove described wliich consists in that said. roller, by the movement of the driving shaft- '23, leve'r rod combination 49 and guide rail 47, actuates the lever 30 andthereby the punching knife 32, thus resulting in the punching operatlon, the same roller 18 further serves to guide the lever 30 in through 4'0 a perpendicular plane.

The rollers 24, 24 whereonthe paper winds and unwinds itself are mounted in bearings I o.n tbo upper or value slide 16; the paper 31 running over these rollers being kept in tension by means of a number :of tension rollers 75, 76, 77 and the tension cord 74. The upper slide 16 moves by means of rollers 84 over lower or time or measure slide 15- bu t isat first rigidly connected there- 50 with bythe nuts 104, Fig. 14, whicl i engage at onc end with the screw spindle 11 of the upperslide. 16 and on the other end are. mounted on the. lower slide 15 is such manner that they cannot be dis laced. The slide 15 can 35 be displaced in he longitudinal direction along the table of the apparatus by means of thcscrcw pindle 19 which can he moved by means of a not which is rotatablv mounted in the frame of the apparatus and b means no of the chain 1!) can be actuated by the hand wheel 55. in order to arrange the-pa )er in its proper working position it is'in the lrst instance adjuslcd by means of the hand wheel 45 (Figs. 1

r. and 10) in such relative time or measure position as is required for the note or the note band. This tune or measure position 18 the 1 initial position occupied b v the punch 32 at l the time when the punching of a cut for a- I note is to be conunenced. For the purpose l at indicating the position of the slide 15 two or three scales 56, 57, (Figs. 4, S and 9) are arranged on working table 1. One of these scales shows the division of the measure into 1, l, f and while the other scale 57 fixes the same values in triplets. It is also possible to arrange. a third scale for in: termediate values, such as hfths, sevenths,i

ninths, tenths, etc.

The division of the time or measure on the l scales is produced by pairs of indicators or pointers 58, 5S, and 59, 59, (Fig. 4), guided on the sides of the scales.

6O (Fi 4) isnn indicator or pointer for a third sca e which may be arranged if desired for fifths, etc. I The mechanical device required for placing the paper band 31 in its initial position con sists of a slide, the so-called lower or time or measure slide 15 (Figs. 1 and 14), which can be adjusted by band by means of an adjust ing wheel, 55, chain 19'- and spindle 19, in ac-' cordance. with the scale. and in such a way that its movement is strictly controlled, the. movement of this slide 15 being transmitted by means of rod combination (i2 and 63 (Figs. 1 and 4) to the indicator scales 56 and 57. At the. some time the paper 31 is by this means placed in its right position in order to be.- brought under the influence of the punching knife. 1

In addition to the lower, or time or measure slide referred to, the. machine possesses an upper slide 16 (Figs. 1 and 14), the so-called value. slide, whose task is to advance by jerks orste s the paper band adjustmenthnd guided )y the time or measure slide 15 in conformity with the. upward movement of the much 32 to punch the slits.

The mechanical dcvicc by which this movement by jerks or steps is obtained consists mainly of a spindle 21 (Figs. 1 and 14), that part of the spindle which faces the slide ci u.: provided with a screw thrcad, vhile l the r st of the spindle is given the shape of a Ill square. 61 (Fig. 14), for the purpose nl' boing turned by means of a ratchet sheave ()4 belonging to ratchet gear 24) (Figs. :2, ll, 14 and- Every time. the spindle 21 is actuated an angle of is performed. or in other words it receives a third of :1 complete revolution.

Ratchet sheave 64. which is secured by l Means of wedges on spindle 31 (Figs. .2. 3, 14

and 15) is 'uctu'atedby mnin shaft 23. to-

'The upper arm oilever 20 carries a trip 67, and the thumb or dent 20 of this trip catches on corresponding contact surfaces formed on 5 the transporting sheave 64 and turns said sheave 64 every time main shaft .23 is'opcrated to tlie'extent of 120, the movement of this sheave being transmitted by it. to the 11 per slide 16. T he toothed sheave. 64, (Fig. 3, is moreover provided with ratchetmechanism. 105, 109, the pawl 10!) of which is continuously pressed' by means a of the spiral s )ring 108 against. the rear lialf of the periphery of the toothed wheel'ti lj This half of the wheel, like the other half, is irovided with three, teeth with the difference however, that the latter teeth are arranged in the opposite direction to'the former.-

By means of the connecting rod 106 which is actuated in a vertical direction from the main shaft 21} the ratchet gear 105, 10:) is periodically caused to come out of engagement with the toothed wheel 64 by means of the spring mounted stop 107. The ratchet of an adjustable head 106 which onits downward travel engages with the projection 107 slide 15.

gear 105, 109 causes the toothed wheel 64 when acted upon by the lever 20 to rotate to the extent o exactly 120. At. the lower end of the arm 105 there is pivoted a projection 107 which can swing upwards on the pivot 107 but islprcvented from swinging. downwards, a connecting rod 106 is vertically movableup and down by means of the rock shaft 23 through thearm65 in the path of the projection 107. Whileanoving upwards the connect ng rod 106 swings the projection 107 round its pivot 107- by means and thereby releases the lever 105 and with itthe detent 109; The upper slide or value slide .16 is actuated by the spindle 21 (Figs.

The upper slide or value slide -'16, which is impelled by mandrel .21, is displaced proportionately to the value. of the'note to bepum'ln-d; the displacement in question being obtained by pressing upward and' downward {not lever 22, which actuates the shaft 23 (Figs. ti'und 7) and whose movement is transmitted t theratchct. gear 20 (Figs. 2, 3,15 and 16) above'refcrrcd to. By

this means the spindle21 is turned every time foot lever 32 is pressed downwards to a 1 given angle, and the frame 16 conr1ccted to l 3 this spindle is displaced a distance which correspondsto the shortest interval. The L return of theupper slide 16 into its initial position upon the lower slide 15 is effected by 5 land by mcansof the hand wheel 45, (Figs. 1 1, 10 and 16) the chain 44",- and the nut 40,

The paper is stretched so to be given the necessary tension required for punching in stretching cord 74 (Fig. 12) which, starting from a roller 75, is passed over guide rollers 76, said'guide. rollers being carried by a. pivoted lever 76 under the action of a spring77 to a second roller (Fig. 1). The spiral spindle oi the lever 76 serves the purpose of moving the rollers 76 in the direct-ion of the arrow and of putting the wire 74 under tension, and thus stretching the paper strip tightly over the drums 24.

In order to count the number of patterntions punched, a counting device 86 of the usual construction is arranged, being actuated from the main shaft 23, it is necessary to ascertain for each note the accurate number of puncliii'igs, in order to obtain a right length of cuts or the proper value of the note.

In order to transmit to the paper strip 3], which .is rigidly connected with the upper slide 16, in accordance with the composition of notes submitted, a time or measure consisting of several notes, and possibly also of several chords, the punch 32 is adjusted with the assistance of hand lever 36 to the first note (for instance a half note), whereupon the machine is started by means of foot lever 22. Punch 32 now punches a slit in tlieptiper strip, which is'siinultaneously advanced with the assistance of spindle '21 and slide 16, the. length of the slit thus produced being perfectly correct irovided the counting device 86 indicates the necessary number of lifts (for instance 48). punched, and provided. the time or measure contains no further note, either'higher or lower, the counting apiaratus at the same time being automatically brought back to zero. started, paper band 31 is returned by means of'gear 44 and 45, and by meansof the screw mechanism 40, 2] to the commencement of the time. or measure, the. upper slide 16 is moved back to its initial po ition on the lower slide 15 which meanwhile remains Slittioimry. if the next note does not commence with the commencement of the measure, or if the first note is followed by a note of the same pitch after a comparatively shortintcrval, it is necessary to advance paper band 31 witlithe assistance of spindle 21, a certain number of smallestintervals and consequently an equal number of lifts of the lever .22, the punch 32 being thrown out of gear. This throwing out of gear is effected After the note has been.

In this manner each note of a measure can be placed in its accurate position on the iaper band; After the completion of the bar the clamping device so, 81 which is mounted on the inside" of the frame of the apparatus at-SS, holds the paper. 31 in'position, whereupon the upper and lower slides l6, 15, are together moved back to the. extent of a'bar, while. the paper 31 is held back relatively to the frame of the apparatus, the iaper winding aiidunwinding itself on the rol eis 2-1 in the meantime to the extent of a bar. When this operation has been effected the cl'anipiii device connected 'with the frame at 83 is re eased, so that the paper 31 can by means of the lower slide-15 0 brought into the correct initial position for punching the tiist note of tlie 'next bar.
